[0030] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further explained in detail below in combination with specific embodiments and with reference to the drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0031] It is understood that the description is only exemplary and is not intended to limit the scope of the utility model.

[0032] The utility model is described below in combination with the accompanying drawings Figures 1-5 Some embodiments of the utility model provide a stainless steel pipe inner pipe wall oil removal core pipe clamping conveying mechanism.

[0033] A stainless steel pipe inner pipe wall oil removal core pipe clamping conveying mechanism, comprising: a base 100, a guide pipe 200, a conveying guide assembly 300 and an adjusting assembly 400.

[0034] The structure of the embodiment comprises: the base 100 is a rectangular frame structure, and the conveying guide assembly 300 and the adjusting assembly 400 are mounted inside. The side wall of the base 100 is provided with an operating opening, facilitating the installation and adjustment of the operator.

[0035] The guide pipe 200 is fixedly installed on the surface of the base 100 and cooperates with the conveying guide assembly 300.

[0036] The inside of the guide pipe 200 is provided with a wear-resistant coating or a corrosion-resistant coating, which can reduce the friction loss and corrosion damage of the oil removal core pipe during the conveying process. One end of the guide pipe 200 is connected with the conveying path of the oil removal core pipe, and the other end is connected with the base 100.

[0037] The conveying guide assembly 300 in the embodiment is used for clamping and conveying the oil removal core pipe.

[0038] The fixed seat 310 is installed on the bottom surface of the base 100, and the fixed seat 310 is provided with two symmetrical mounting holes for mounting the first rotating shaft 320 and the second rotating shaft 330.

[0039] The first connecting lug 311 and the second connecting lug 312 are hingedly connected with the fixing seat 310 through an axle pin, and form a structure that can be relatively deflected.

[0040] The first rotating shaft 320 and the second rotating shaft 330 are sleeved on the second connecting lug 312 through a sliding structure and can slide in an axial direction.

[0041] The first rotating shaft 320 and the second rotating shaft 330 are respectively fixedly installed with a transmission tooth 313 and a wheel 314 on surfaces thereof.

[0042] The driving tooth disc 340 is fixedly connected with the second rotating shaft 330 through a spline structure.

[0043] The adjusting assembly 400 is used for adjusting the distance between the first rotating shaft 320 and the second rotating shaft 330 in the embodiment, so that the oil removal core pipes with different diameters can be matched.

[0044] The ratchet tooth disc 410 is fixedly arranged on the top of the base 100 through a threaded structure.

[0045] The operating rod 420 is fixedly connected with the ratchet tooth disc 410 and can rotate above the ratchet tooth disc 410.

[0046] The ratchet tooth piece 430 is engaged with the surface of the ratchet tooth disc 410 through a spring structure, so that the ratchet tooth disc 410 can keep a stable position during adjustment.

[0047] The working principle and the use process of the utility model are as follows:

[0048] The utility model relates to a kind of stainless steel pipe inner tube wall oil-removing core pipe clamping conveying mechanism, the linkage structure of conveying guide assembly 300 and adjusting assembly 400, realize the automatic clamping, accurate conveying and synchronous adjusting function of oil-removing core pipe, ensure stable clamping in conveying process, improve conveying efficiency and precision.The complete working principle is as follows:

[0049] 1. Initial assembly and preparation: before use, the operator first inserts the oil-removing core pipe into the catheter 200 by installation operation.

[0050] The catheter 200 is coated with a wear-resistant or corrosion-resistant coating on the inside to reduce friction and corrosion during transportation.

[0051] The operator manually deflects the ratchet piece 430 to disengage from the surface of the ratchet tooth disc 410, and controls the operating rod 420, thereby controlling the ratchet tooth disc 410 to deflect to the initial position, so that the first rotating shaft 320 and the second rotating shaft 330 are in a loose state, facilitating the insertion of the oil-removing core pipe.

[0052] 2. Automatic adjustment and locking of the clamping mechanism: after the oil-removing core pipe is inserted into the catheter 200, the operator controls the deflection of the ratchet tooth disc 410 by rotating the operating rod 420.

[0053] During the deflection of the ratchet tooth disc 410, the guide sleeve groove 411 guides the synchronous sliding of the first rotating shaft 320 and the second rotating shaft 330, and pushes the two abutting wheels 314 radially inward.

[0054] The abutting wheels 314 are in close contact with the inner wall of the catheter 200 through sliding, achieving clamping of the oil-removing core pipe.

[0055] After the ratchet tooth disc 410 is deflected to the set angle, the ratchet piece 430 engages with the surface of the ratchet tooth disc 410, forming a meshing locking effect, ensuring that the ratchet tooth disc 410 remains stable under external force, preventing the clamping from loosening.

[0056] During the locking process, the torsional spring on the surface of the ratchet piece 430 generates a reverse torsional force to maintain the engagement of the ratchet piece 430 with the surface of the ratchet tooth disc 410, further enhancing the locking stability.

[0057] 3. Transmission and conveying process: after the clamping mechanism is locked, the drive gear 340 is driven to rotate by an external motor.

[0058] The drive gear 340 drives the first rotating shaft 320 and the second rotating shaft 330 to rotate synchronously through the transmission teeth 313.

[0059] During the rotation of the first rotating shaft 320 and the second rotating shaft 330, the abutting wheel 314 is in close contact with the inner wall surface of the oil removing core pipe, and the oil removing core pipe is driven to rotate and convey synchronously through the friction force.

[0060] Since the first connecting lug 311 and the second connecting lug 312 are connected through the shaft pin, the two abutting wheels 314 can rotate synchronously during the deflection, and uniform clamping and conveying of the oil removing core pipe are ensured.

[0061] 4. Clamping distance adjustment function: during the conveying of the oil removing core pipe with different diameters, the operator can adjust the deflection angle of the ratchet tooth disc 410 through manual or automatic mode.

[0062] During the deflection of the ratchet tooth disc 410, the guide sleeve groove 411 slides to guide the first rotating shaft 320 and the second rotating shaft 330, so that the distance between the two abutting wheels 314 is synchronously increased or reduced to adapt to the oil removing core pipe with different diameters.

[0063] The stable locking state is formed through the meshing contact between the ratchet tooth plate 430 and the ratchet tooth disc 410, so that the clamping distance is kept constant during the conveying process, and loosening is prevented.

[0064] In summary, through the linkage structure design of the ratchet tooth disc 410, the ratchet tooth plate 430, the first rotating shaft 320 and the second rotating shaft 330, automatic clamping, synchronous conveying and automatic adjustment of the oil removing core pipe are realized. The compact structure design is simple to operate, and is suitable for high-precision conveying operation of the oil removing core pipe with different diameters, and the applicability and working efficiency of the equipment are improved.
